an employess new salary is 28,140 after getting 5% raise what was salary before increase _and what was last years salary _?
jonny [76]
He got a 5% raise, so 28,140 is 105% of what it used to be.

105% means 1.05

(1.05) x (salary before increase) = 28,140

Divide each side by 1.05 :

Salary before increase = 28,140 / 1.05 = <u>26,800</u> .

The rest of the question is nonsense. The salary
before increase IS last year's salary.

Greetings from Brasil...

Here we don't have much to go

∛Y = A.(C + 1/X)

∛Y = (AC + A/X)

raising both members to the cube.....

(∛Y)³ = (AC + A/X)³

from Notable Products: (a + b)³ = a³ + 3a²b + 3ab² + b³

Y = (AC)³ + 3(AC)².(A/X) + 3AC(A/X)² + (A/X)³

Y = A³[C³ + (3C²/X) + (3C/X²) + (1/X³)]

The volume = 2143.573 cubic inches

Step-by-step explanation:

∵ The volume of the sphere = \frac{4}{3}\pi r^{3}

∵ The diameter of the sphere is 16 inches

∴ Its radius = 16 ÷ 2 = 8 inches

∵ The fishbowl is filled

∴ The volume of the water = the volume of the fishbowl

∴ The volume of the water = \frac{4}{3}\pi(8^{3})=2143.573 cubic inches
